CULTIVATOR ATTACHMENT.

Application filed July 18, 1913.

To all whom it may concern:

Be it known that I, AMMoN Wool), a citizen of the United States, residing at Covington, in the county of Tipton and State of Tennessee, have invented new and useful Improvements in Cultivator Attachments, of which the following is a specification.

This invention has relation to scraper attachments especially adapted to be applied to cultivators and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide an attachment of the character indicated which may be easily and quickly applied to l the foot of a standard of a cultivator and which may be readily adjusted in order that the scraper blade may be pitched at a desired angle with relation to a horizontal and may also be adjusted vertically in order to cut at different depths in the soil.

WVith the above object in view the attachment includes a plate having angularly disposed end portions, one end portion being adapted to travel along the surface of the ground when the plate is applied to the foot of the cultivator standard. The other end portion of the plate is provided with a bolt perforation through which the pivot bolt is passed which secures the plate to the said foot. An arcuate slot is provided in the said end portions of the plate, the said are being struck from the said bolt perforation as a center. At the opposite sides of the said bolt perforation are arranged parallel slots. The said arcuate slot is adapted to receive a bolt carried by the said foot whereby the plate may be pitched at a desired angle with relation to a horizontal. A scraper blade is located against the said portion of the plate which is provided with the perforation and slot and bolts pass transversely through the scraper blade and through the said parallel slots and thus the said scraper blade may be adjusted vertically with relation to the said plate. I

In the accompanying drawing :-Figure 1 is a perspective view of the plate of the attachment. The other figures are detailed views of the various features of the device.

As illustrated in the accompanying drawing the cultivator standard 1 is provided at its lower end with the usual foot block 2 which in fact is a part of the standard. The standa d 1 may be of any app o ed Specification of Letters Patent.

pattern, that is to say the standard may be rigid or of the spring type. The attachment comprises a plate 3 having angularly disposed portions 4: and 5, when the plate 3 is applied to the foot block 2 the portion 4 is adapted to travel along the surface of the soil at the bottom of a furrow and limit the depth at which the blade mounted thereon and which will be hereinafter described will operate in the soil.

The portion 5 of the plate 3 is provided with a bolt aperture 6' through which a bolt may be passed for securing the plate 3 to the lower end portion of the foot block 2 upon the standard 1. The portion 5 of the plate 3 is further provided with an arcuate slot 7 the center from which the said are is struck is coincident with the center of the aperture 6. The said slot 7 is adapted to receive a bolt which is carried at the upper portion of the foot block 2 and by loosening the bolt which is located in the arcuate slot 7 the plate 3 may be turned on the bolt which passes through the aperture 6 in order that the said plate may be pitched at a desired angle with relation toa horizontal. The portion 5 of the plate 3 is provided at the opposite side of the aperture 6 with elongated slots 8 which are parallel. A scraper blade 9 is positioned at the forward surface of the portion 5 of the plate 3 and bolts 10 pass transversely through the blade 9 and through the slots 8. By loosening the bolt 10 the scraper blade 9 may be adjusted vertically with relation to the plate 3 whereby the lower portion of the blade 9 may project more or less below the lower surface of the portion 4: of the plate 3 in order that the depth at which the lower portion of the blade 9 may operate in the soil is regulated.

Having described the invention What is claimed is In combination with a standard, a plate having angularly disposed portions one of which lies against the standard and the other passing under the standard and spaced from the ends thereof, that portion of the plate which lies against the standard being pivoted to the standard for swinging movement transversely thereof and provided with an arcuate slot concentric with said pivot, a bolt passing through said slot and engaging the standa d Whflfi y the plate may be swung transversely of the parallel slots and adjustably secured standard and secured With relation thereto, therein. 10 said portion of the plate also having at the In testimony whereof I afiiX my signature opposite sides of the bolt aperture and bein presence of tWo Witnesses.
